The former is produced by the decomposition of [Ni(CO)4] vapor after distillation and purification, forming suitable-shaped nickel particles by controlling temperature under dilution and with the presence of gas additives (oxygen and nitrogen), followed by washing with a solvent and controlling the oxygen content on the particle surface to 0.065%. The latter is made from high-purity nickel powder, formed into suitable thickness flakes by grinding in a ball mill with steel balls under the presence of suitable lubricants and liquid mediums.
